$def with (course, taskid, task_data)

<p>This is an example tab for course "$course.get_name("en")" (id: "$course.get_id()"), and task "$taskid". We can show data
from the task descriptor, such as the name "$task_data.get('name', '')"</p>

<p>We can also include some data for a form:</p>

<div class="form-group row">
    <label for="example_task_hint" class="col-sm-4 control-label">Task hint</label>
    <div class="col-sm-8">
        <input type="text" class="form-control" id="example_task_hint" name="example_task_hint"
          value="${task_data.get('example_task_hint', '')}">
    </div>
</div>

<p>Note that form data needs to be processed by a separate hook</p>
